Electromagnetic Waves
Transverse waves consisting of changing electric fields and changing magnetic fields.
What is a electromagnetic wave?
Full range of frequencies of Electromagnetic radiation.
What is the Electromagnetic Spectrum?
False or distorted image from refraction
What is a mirage?
behavior of light depends on materials that an object is made of.
What is one factor of light behavior?
Objects that give off their own light.
What are Luminous objects?
When an electric charge vibrates or accelerates.
How is a electromagnetic wave produced?
Radio waves, infrared waves, visible light, ultraviolet rays, x-rays, and gamma rays.
What waves do the Electromagnetic Spectrum include?
Light waves that vibrate in only one plane.
What is polarization?
Material scatters light.
What is translucent material?
Device that generates a beam of coherent light.
What is a Laser?
How they are produced and how they travel.
How are electromagnetic waves different from mechanical waves?
Wave with the highest frequencies.
What is one characteristic of Gamma Rays?
A copy of an object formed by reflected or refracted waves of light.
What is am image?
Material absorbs or reflects all light.
What is opaque material?
What is phosphor?
By magnets-by changing electric fields and vibrating charges.
How are magnetic fields produced?
To discover heat differences.
What is one use of Infrared Rays?
Light can be reflected, absorbed or transmitted.
What happens when light strikes a new medium?
material that transmits light
what is transparent material?
Light produced when an object gets hot enough to glow.
What are incandescent lights?
Transfer of energy by electromagnetic waves traveling through matter or empty space.
What is electromagnetic radiation?
Wavelength of 12nm to 0.005nm
What is the length of X-Rays?
Light is redirected as it passes through a medium.
What is scattering?
Objects do not allow light or pass through.
What is opaque material?
Bulbs made of quartz which has a higher melting point than glass.
What is one requirement for tungsten halogen light bulbs?
